I've been doing the nim track on exercism.io (no affiliation, just a user) for the last two weeks. The mentors on the track have been fantastic. If you're looking for a "solve a problem and get some external feedback" approach to learning the language it's pretty good.
Personally I stopped using exercism, when it started to require me to work for Google for free and would not let me log in, if I did not. It's not an ethical platform, unfortunately.
Exercism co-founder here. We get bots spamming the site in every way possible if we don't have a recaptcha. Happy to accept other suggestions for stopping bots signing up if you have any more ethical alternatives that are as an effective?
Perhaps I would. I've supported many projects in the past, so I think, if it was really good and did not violate my privacy, there is a fair chance I would.
